Release: Service Annual Survey
Starting with the 2018 Service Annual Survey, the number of detailed operating expense items have been reduced, so this series has been discontinued. These expenses will now be captured within the "All other operating expenses" item for the industry. For more information, see the press release that contains the changes to operating expense items.
